In general, it is ultraviolet light (the UV ray) that causes sunburn. Ultraviolet light is of a higher frequency than visible light, which means shorter wavelength, and higher energy. UV rays tend to do some tissue damage and burn skin causing sunburn.
UV radiation is of a high energy, therefore it can cause damage to living cells. The dangers faced by humans include; most commonly damage to the skin, but also damage to the eye and immune system. Most people experience sunburn at some time in their lives, but UV can cause more serious skin damage such as cancer as a result of DNA damage.
Do you mean 'Which electromagnetic wave in the electromagnetic spectrum causes sunburn? The answer is Ultraviolet (UV), which is what is used in sunbeds and therefore damages and colours your skin cells.
No. Sunburn would be an example of absorbed energy.
If by energy you mean light then yes. Over exposure to UV light causes skin cancer and melanomas.
skin tanning due to sunburn will depend on one's melanin content; for people of color, skin tends to darken easily; because they have more melanin pigments on their skin. :-)

Excessive heat. When cells are exposed to sunlight, radiant energy can damage DNA.
Dependence on fossil fuels causes environmental damage.

Electromagnetic energy waves on the UV light spectrum.Ultraviolet.UVB
In short, sunlight is made of light waves. These light waves are of various energies. The small band of energy we can see is called the visible spectrum. These waves are not dangerous to us. There are light waves that are slightly higher in energy these are known as Ultra Violet(UV) rays. These rays contain enough energy to penetrate your skin cells and cause damage to your DNA. This damage can lead to serious side effects such as skin cancer if you body is unable to properly repair the damage. Luckily the vast majority of the time your body is able to repair the damage through a number of highly complex DNA repair mechanisms.
